Andrew Purtell commented on PHOENIX-2629:
-----------------------------------------
Just be sure to track the source classes for possible evolution.... As in this
case, HBase might fix a data loss bug on some version of HDFS but Phoenix would
still be vulnerable. Maybe we should sync up PMC to PMC at every release and go
over the change logs?
